At naaa iiledDecemher 23,1897. Serial N'Q- 663,191. (llomodelfl To all whom it may concern:

Be it known that I, ALBERT ERNs'r THEO- DOR DALLMER, a subject of the King of Saxony, residing at Dresden, Saxony, Germany, have invented certain new and useful Improvenientsin or Relating to Automatic Coin- Freed Apparatus, of which the following is a specification.

The automatic coin-freed apparatus according to the present invention is particularly adapted for the sale or delivery of fiat rectangular objects, more particularly for postcards, railway-tickets, and similar articles and also for thin packets of chocolate or the like. The goods are arranged so that articles placed in a transverse direction alternate with those placed in a longitudinal direction, the articles crossing each other. The whole heap has therefore the shape of a Geneva cross. A disk guiding and turning the goods is provided with a corresponding opening or recess. The Whole stock or pack would therefore fall through it were it not for two fixed segment-shaped supports arranged within the opening and leaving between them a free space equal to the width of one article or packet of goods. The lowest packet always rests on these two supports; but this packet can fall through when the disk, with the stock of goods, is turned through an angle of ninety degrees. Then the packet resting on the supports comes into the position of the free space between the supports and falls through, the next packet, which now becomes the lowest, being held by the support. An inclined plane, guiding the article falling through to the outside of the casing, clockwork mechanism employed to turn the disk and the goods through an angle of ninety degrees each time it is released by a coin, and the outside casing complete the apparatus, two constructions of which are shown in the accompanying drawings.

Figure 1 is an elevation of the apparatus according to the present invention, being a transverse section through the casing and inclined plane. Fig. 2 is a longitudinal sectional elevation through the casing, goodssupporting disk, and the inclined plane. Fig. 3 is a plan, the cover of the casing and the goods being removed. Fig. 4 is a cross-section on lineaet of Fig. 1. Figs. 5 to 7 are detail views of certain parts of the pawl and re- I leasing mechanism in different positions. All these figures represent the first construction. Figs. 8 and 9 are a plan and elevation, respectively, of a modified form of apparatus.

In a casing A ofany desired outward shape closed at the top by a cover A, Fig. 1,.there is arranged a foundation-plate B. In the bearing 1 in the center of the plate B there is secured a vertical rod 2. Its upper end carries a cross-bar 3, the latter carrying rods 4:, carrying the supports 0, Figs. 1, 2, and 3.

A tubular shaft 5 is rotatable about the rod 2. This shaft is provided at its upper end with a cross-piece 6, provided with two uprights 7, carrying the disk D. The disk is arranged in the horizontal plane of the supports 0 and is provided with an opening of the shape of a Geneva cross, Fig. 3. Each of the two rectangular openings forming the cross corresponds in its length and width to the dimensions of an article to be sold. Around the openings there are secured to D upwardlyprojecting pins or rods (1, which may be replaced by walls of the same cross-section as the cross. Between these pins or walls are placed one on another the articles 00, Figs. 1 and 2. The lowest article is placed over that part of the opening which, according to Fig. 3, lies for the moment longitudinally over the two supports 0, so that said article rests on these supports. The second article is placed transversely, so that it rests in the center on the first one. The third is again placed longitudinally, and so on, till the stock of goods reaches up to the top of the rods 01 d.

Each time that the disk is turned through an angle of ninety degrees the lowest article will come into a position transversely of the supports and falls through, the next article being held by the supports coming under it.

In order to guide the article which has fallen through to the outside,there is arranged transversely of the supports 0 two inclined planes E E, which guide the article to the outside through an opening 6, Fig. 2, outside of which is a receiver E Figs. 2 and 3. The front end of the article slides into this receiver'and can be seized with two fingers and easily withdrawn. and E there is an opening (shown in Fig. 2) through which the cross-piece 6 and the rods Between the inclined planes E 7 pass when the disk D is turned. The parts are so arranged that they cannot block the opening so as to prevent the article from sliding out. The part E is secured to the fixed rods 4 by means of rings as or otherwise.

The movement of the disk D is effected by clockwork or other mechanism substantially of well-known construction. F, Figs. 1 and 4, is the spring-barrel, which rotates the hollow shaft 5 by means of a toothed wheel 8, pinion 0, spindle 10, and bevel-wheels 11 and 12. The speed is regulated by means of a flying pinion F, which is driven (the transmission-gearing being very high) from the toothed wheel 8 by means of a pinion 14, spindle 13, and wheel 15, spindle 16 carrying pinion 17 and wheel 18 and spindle 19 carrying pinion 20 and wheel 21, Fig. 4. The latter wheel engages with the worm 22 on the vertical spindlef of the flying pinion, Fig. 1. This mechanism must be released by the introduction of a coin and automatically stop after the disk D has made one-quarter of a revolution. The releasing and the stopping are effected at the flying pinion in substantially well-known manner, the moment of stopping being determined by the hollow shaft 5, which has to turn each time through an angle of ninety degrees. Three levers are used for this purpose-the counterweighted coin-lever G, which chiefly has to effect the release of the mechanism, the pawl H, operated by the coin-lever to lock or to release the mechanism, the locking action of said pawl being regulated from the hollow shaft 5, and the pivoted lever I, cooperating to regulate the action of the pawl H.

The coin-lever G is pivoted at 23, Figs. 1 and 4:, and carries at its front end a plate 9 and a weight g at its other end, which may be replaced by a spring. The plate 9 is situated under the mouth of the coin-chute 24:, Fig. 1, dotted lines, extending from the coinslot 25, Fig. Under the foundation-plate B there is arranged beneath the plate ga till or coin-receiver 26. \Vhen the coin introduced falls on the plate g, the lever G is depressed. The coin then slides down from the plate and the lever G immediately swings back. The one-armed lever or pawl H, pivoted at 27, Fig. 4-, rests with its front end on the left-hand arm of the rod G and is there fore raised by the weight g. The lever II carries a pin 28, which comes into the path of the arm 29 on the spindle f of the flying pinion, Fig. 1, when the pawl H is in its highest position. This highest position takes place each quarter of a revolution, one of the notches of the disk 31 on the hollow shaft 5 coming during the rotation over the pin 36 on the lever 1-], Figs. 1 and 5. The pin then engages with the notch under the influence of the weight 9'. During the momentary swinging of the lever G under the weight of the coin the lever H descends into its lowest position. This disengages the arm 29 from the pin 28 and the mechanism can rotate.

As, however, the swinging of the coin-lever is only momentary, whereas the rotation of the hollow shaft 5, on the contrary, is comparatively slow, the pin 30 would, when the lever G becomes disengaged and returns, again engage with the notch, which is still situated over it. This is prevented by the lever I, the arrangement and working of which will be best understood by referring to Figs. 5 to 7. This lever I, pivoted at 32, engages with the pin 32 of the lever II under the influence of its own weight or a spring. The pin 32 maybe made in one piece with the pin 30. In Fig. 5 the lever II is in its highest position. When during the swinging of the coin-lever the lever H comes into its lowest position, Fig. 6, a notch t' of the let er I at once engages with the pin 32. Thus the lever II cannot for a time swing upward. The mechanism is therefore free to rotate, and the corresponding notch of the disk 31 passes away over the pin 30. Then the lever I must be disengaged to enable the pin 30 to engage with the next approaching notch of the disk 31. For this purpose there is mounted on the hollow spindle 5 four tappets 33, (see Fig. 4,) the tappets being arranged to alternate with the notches. pets strikes at the desired moment the lever I and presses it back for an instant. The pin 32 is thereby released and the lever II swings upward until the pin 30 rests against the lower edge of the disk 31. This is the central position of the lever 11, as shown in Fig. 7, in which the pin 28 still leaves the spindle of the flying pinion free. This position is maintained until the next notch of the disk 31 comes over the pin 30. Then the lever II rises to its highest position and the parts are again in the position shown in Fig. 5, in which the mechanism is locked.

Each time that a coin is inserted the mechanism is released, the disk D makes a quarter-revolution, and a pocket of goods is discharged. In this construction the disk D progressively turns in the same direction, while in the second construction, according to the present invention, the disk D is caused to rockthat is to say, the disk is caused to turn through an angle of ninety degrees in one direction when the mechanism is released, while the succeeding release causes it to turn back in the opposite direction, also through an angle of ninety degrees.

In the construction illustrated in Figs. 8 and 9 the hollow shaft 5 is caused to turn from the spring-barrel F in the manner already described, but in this case each time through an angle of one hundred and eighty degrees. The disk 31 is accordingly provided only with two notches, to which correspond two tappets On the hollow shaft 5 is secured a crank 34., connected by a rod 35 with the cross-piece 6,which rotates about or with a separate spindle 36. At each revolution of the crank 34: the part 6, together with the uprights 7 and disk D, makes one-quarter of a One of the tapand effect the release revolution-4. e., the cross-piece 6 rocks between the positions shown in broken lines and in combined broken lines and dots, Fig. 8. The supports 0 are carried by rods 4, extending downward to the foundation-plate B. The

rods are arranged in such manner and the cross-piece 6 is of such shape that the former leave the latter sufficient freedom of motion, as clearly shown in Fig.8. In this construction the inclined plane E E need not be divided, as will be seen on examining the path of the parts 6' and 7.

Various changes may be made in the-construction of the apparatus without departing from the spirit of myinvention. For instance, other forms of motors may be employed in lieu of the spring-motor illustrated.
